In this review we summarise the current status of the quasi-static magnetohydrodynamic turbulence. The energy spectrum is steeper than Kolmogorov's k -5/3 spectrum due to the decrease of the kinetic energy flux with wavenumber k as a result of Joule dissipation. The spectral index decreases with the increase of interaction parameter. The flow is quasi two-dimensional with strong [Formula: see text] at small k and weak [Formula: see text] at large k, where [Formula: see text] and [Formula: see text] are the perpendicular and parallel components of velocity relative to the external magnetic field. For small k, the energy flux of [Formula: see text] is negative, but for large k, the energy flux of [Formula: see text] is positive. Pressure mediates the energy transfer from [Formula: see text] to [Formula: see text].

准静态磁流体动力学湍流中的各向异性

在这篇综述中，我们总结了准静态磁流体动力学湍流的现状。由于焦耳耗散导致动能通量随波数 k 减小，因此能谱比 Kolmogorov 的 k -5/3 谱更陡峭。光谱指数随着相互作用参数的增加而降低。流是准二维的，小 k 处强 [公式：见正文]，大 k 处弱 [公式：见正文]，其中 [公式：见正文] 和 [公式：见正文] 是垂直和平行分量相对于外部磁场的速度。对于小k，[公式：见正文]的能量通量为负，但对于大k，[公式：见正文]的能量通量为正。压力介导了从[公式：见正文]到[公式：见正文]的能量转移。
